Why should I buy a home warranty when I purchase a house?

Home warranties usually cover the operational aspects of a home, and even afer having a home inspection. The $2-4 hundred dollars cost will be well spent if you have to replace a central unit or even 2 or more items in a short time. This is also dependent on your emergency fund and cash solvency.

Would you buy a refurbished computer or tablet? Why or why not?They are a lot cheaper, but I have to wonder if buying new is the only thing that makes sense with electronics of that nature. They seem to become obsolete...
